Everyday Items Around Your Homes That Attract Mosquitoes

Where Do Mosquitoes Lay Eggs?
All mosquito species require water to breed and complete their lifecycle. Mosquitoes lay their eggs in or near stagnant water, where they hatch into fully aquatic larvae. The larvae feed and develop in the water until they pupate, leaving only after the fully mature adult emerges from the pupa and flies off. However, different mosquito species require different water sources, and each source can be categorized into one of three groups: permanent water mosquitoes, floodwater mosquitoes, and container mosquitoes.

Permanent Water:
These mosquitoes seek out large standing water sources, such as stagnant ponds and marshes, to breed. Many species will lay their eggs directly on the water’s surface, while others will lay their eggs on aquatic plants. Most mosquitoes will seek out freshwater sources; however, some mosquito species are able to breed in coastal salt marshes.

Floodwater:
While all mosquito eggs need water to hatch, some species are capable of “waiting it out.” Floodwater mosquitoes lay their eggs on or just above the water line of plants or other aquatic structures near ditches or floodplains. The eggs are able to survive in a dormant state when these places are relatively dry, and then hatch when they flood. This can lead to large, localized spikes in mosquito numbers after heavy rainfall, when many of these mosquitoes’ eggs hatch simultaneously.

Containers:
Container-breeding mosquitoes lay their eggs in nearly anything capable of holding water. Common sources often include artificial containers such as discarded tires, buckets, and bird baths and natural containers such as tree holes or leaf axils of plants. Container mosquitoes are especially problematic in urban areas and suburban areas where many of these containers are found within the environment. Fortunately, there are plenty of precautions citizens can take to eliminate these breeding sites.

Common Mosquito Breeding Containers Near Homes

Container mosquitoes will use nearly anything that holds water as a breeding site. Containers do not need to be especially large or permanent to host container mosquito larvae. Here are just a few of the small but common containers these mosquitoes will seek out:
Buckets
Flowerpots and planters
Leaf-clogged gutters
Old tires
Wheelbarrows
Bird baths
Trash cans
Swimming pools
Pet dishes
Because some container mosquitoes like Aedes aegypti and Aedes albopictus are potential disease vectors, it can be just as important to monitor container sources as it is permanent water and floodwater sources. Fortunately, there’s plenty the average citizen can do to help eliminate container breeding sites.

What Can Citizens Do to Reduce Mosquito Breeding Sites?

Because of mosquitoes’ quick life cycle, it’s important to limit breeding sites on an ongoing basis, and especially after substantial rainfall. Cleaning up a property and removing any discarded cups, jars, old tires, or other debris is a great start. Ensuring that gardening equipment like wheelbarrows and buckets are either covered or turned over when not in use can prevent them from becoming breeding sites later on. Clearing clogged gutters or planters is a great next step, and draining any larger water sources like unused swimming pools can also go a long way toward limiting the spread of container mosquitoes and potential mosquito-bite diseases.
